An RUAnniversary Party is a party to commemorate the anniversary of the Radioactive Uber Clan. Every part is held at RUC HQ and all kinds of music is being played. Bright lights flash all over while the party is going on and everyone dances.
All kinds of gourmet food is served during the party, all made by Fat Albert.
At the end of the show, Popeye The Sailor usually makes a speech about how he is happy to be with the Radioactive Uber Clan, how his friendships with everyone matters to him, and what his future will bring.
Everyone gets an RUAnniversary T-shirt with the year it was held in on the bottom. Thousands of people come to join the party.
